Perform your shooting skill in Burbles.io and see if you can get the highest score to take over the top rank on the leaderboard or not. In this MSN game, you must shoot at burbles of the same colors for more points and XP, or you can fire other enemies too. The more combinations you make, or the more enemies you kill, you can improve your boat a lot. Be sure to cover up yourself when the enemies try to attack you. Attempt to survive longer to win the battle!
